Or if you have some cheap bottled chocolate sauce, drizzle it over frozen berries. Like ice cream except not.

If you happen to own a good blender or food processor, you can blend frozen bananas with other types of fresh or frozen fruit, and add a sweetener like maple or agave syrup to make "nice cream."

Around Thanksgiving, I made a delicious thing: canned pumpkin mixed with spices (cinnamon will do but you can add nutmeg and cloves or use "pumpkin pie" spice); stick full-fat coconut milk skimmed for just the fatty part (you have to refrigerate a can of coconut milk over night up to one day for this) and blend that thick white fatty part in the blender with maple or agave syrup then place on top of your spiced canned pumpkin. Promptly smack any non-vegan that tries to steal your "pumpkin pie." The thin liquid part from the canned coconut milk can be mixed into a smoothie later or used in another recipe.
